The mind is the strongest of all without a doubt. You're one of them, you'll have the power of someone's mind, complete control. But watch out, the darkness will consume you. Like you're nothing, you'll be his, forever and always. No escaping, no turning back. You won't even know the difference. Although you won't realise, the rest around you certainly does. You'll be haunted, followed and begged for your power. The one wants your blood, the other your love, but then there is one man left. One man, who doesn't now what he wants, yet. Maybe your power? Your status? Or will he use you as bait?
But before that all will come, you'll have to survive some other smaller challenges. They were all planned, the day you were born they knew your destiny, your duty. You are the one who has the power and the potential to do this. You will be the one who saves the Wizarding world. But at the same time you'll be able to do the opposite. Chose wisely. There is no way back once chosen the wrong one.
